PURPOSE:To scrape toner offset on a heat roller by a cleaning blade and to supply oil from an oil coating roller to the heat roller stably for a long period by providing the oil coating roller behind the cleaning blade. CONSTITUTION:The oil coating roller 6 which contains oil is fitted rotatably to roller fitting plate 7 and contacts the heat roller 1, so the oil coating roller 6 rotates by being driven by the heat roller 1 to apply a proper amount of oil uniformly over the surface of the heat roller 1. When the heat roller 1 contacts the oil coating roller 6, there is no dirt such as toner sticking on the surface of the heat roller 1 at any time because the coating roller is arranged behind the cleaning blade 3. Consequently, the surface of the oil coating roller 6 is not stained at any time and its initial surface state is maintained stably for a long period, thereby supplying the oil stably. |
